1)For the reaction

HA(aq) + BOH(aq) BA(aq) + H2O(l) , where HA represents an acid, and BOH represents a base, the temperature rises by 0.320C when 100.0 mL of 0.0500 mol/L HA(aq) and 100.0 mL of 0.0500 mol/L BOH(aq) are mixed in a calorimeter. The specific heat capacity of the solutions is 4.184 J/g C and the density of the solutions is 1.00 g/mL.

15. For the reaction HA + BOH BA+H.0 where HA reprsents an acid and BOH represents a base, the temperature rises by 0.320C when 100.0 mL of LOSOO mol/L/HA and 100.0 mL of 0.0500 mol L BOH are nlived in a calorimeter. The specific heat capacity of the solutions is 41841/g C and the density of the solutions is 1.00 g/ml. From this experimental data, which answer is correct? A) HA + BOH BA +11,0 + 26.8 kJ 20 B) HA + BOHY BA +HO+53.6 kJ C) + OH HO/4-268 kJ D) HA + BOH - BA +H20 AH = -5 36 kJ 16. The decomposition of sulfur tionde is represented by the equation 250 3 198 kJ 250, + 0310 200 B) 50,,, + $0 ) to Based upon this information, which one of the following thermochemical equations is correct? A) SO SO + 20 + 198 kJ SO + 198 kJ SO 21 3 C) SO + 20 200 SO + 99 kJ 30 D) SO SO 20. +99 kJ 300 20 17. The thermochemical reaction for the formation of hydrogen fluoride gas from its elements given by the following equation: + F2HF + 546 kJ From the above equation, it can be stated that A) AH (HF) - - 546 kJ/mol B) the total bond energy in H+Flis 546 kJ less than the bond energy in 2HF 200 C) the total enthalpy in H, +F 27 is 546 kJ higher than the enthalpy in 2HF D) the formation of HF from its elements at standard conditions is endothermic Hie
